I WIRE-TWISTING MACHINE.

Specification of Letters Patent.

Application filed April 10, 1909. Serial No. 489,237.

to the accompanying drawings.

This invention relates to wire twisting machines and more especially toa certain arrangement whereby positive action is obtained with greatsimplicity of construction.

The invention consists in the matters hereinafter set forth and moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 is 'a View in perspective of a machineembodying the inventlon; Fig. 2 is a view in detail of a twisting rollhead and the rolls; Fig. 3 is a View in section on line 0000 of Fi 2.

Referring to the drawings, a flat base 1- has a pair of alined bearinbrackets 2 and 3 in which a main hollow shaft 4 is rotated by a pulley 5between the hearings or by like suitable means. A twisting roll head 6is secured on the inner end of the shaft 4 near the bearings 3. A wormshaft 7 is journaled in this roll head parallel to and a short distancefrom the main shaft. A pinion 8 is secured on the inner end of the wormshaft adjacent the bearing 3 in mesh with a stationary internal gearQconcentric with the main shaft which is secured to or formed integrallyon a suitable upright bracket 10 mounted on the base 1.

A worm 11 on the outer end of the worm shaft meshes with a pair of wormgears 12 which drive roll arbors13 journaled in a set of bearings 14 onthe outer end of the head 6. Rolls 15 with grooved peripheries arecarried by these arbors in such position that they feed wire insertedbetween them through the hollow shaft 4. An angle plate 16 having aslotted foot 17 with clamping cap screw 18 is adjustably secured on thebase 1 so as to be moved to or from the feed rolls. Apertures 19 in thisplate in substantial. axial alinement with the main shaft 4 act as uidesthrough which wire strands indicatetI at 20 may be drawn and inserted inthe rolls.

In operation the gage plate may be moved to or from the feed rolls tomake the wire twist tightly or loosely as preferred. The rotating rollsfeed the twisted wire through the shaft and the machine when onceadjusted maintaining itself with very little attention or care.

Obviously, changesin the details of construction may be made withoutdeparting from the spirit of the invention and I do not care to limitmyself to any particular form or arrangement of parts.

What I claim as my invention is 1. A wire twisting machine comprising abase, a pair of bearing brackets thereon, a horizontal, hollow mainshaft journaled in the brackets, a driving wheel on the shaft betweenthe bearings, a roll head on the shaft, a worm shaft journaled in thehead parallel tov the main shaft, a pinion secured on the Worm shaft, agear bracket on the base, an internal gear concentric with the mainshaft secured in thegear bracket in mesh with the pinion, a pair ofparallel roll 2. A wire twisting machine comprising a base, a pair ofbearing brackets thereon, a

horizontal, hollow main shaft journaled in the brackets, a driving wheelon the shaft between the bearings, a roll head on the shaft, a wormshaft journaled in the head parallel to the main shaft, a pinionsecuredon the worm shaft, an'upright bracket on the base, an internalgear formed integrally on the bracket concentric with the main shaftinmesh with the worm pinion, a pair of roll arbors journaled in parallelrelation in the head transversely to the worm shaft, a Worm pinionsecured on each arbor in mesh with the worm, a peripherally grooved rollon each arbor, said rolls coacting to force wire through the main shaft,an angle plate in axial alinement with the shaft having a pair of guideapertures opposite the feed rolls, a slot-ted foot on the plate, and aclamping screw in the 'base engaglng the slotted foot.

In testimony whereof I afiix my signature in presence of two witnesses.

LOUIS BLESSING.
